WILLIAM G..KIEFER, or naooxnmn, nAssAoHUsET'rs, ASSIGNQR T0 E. VAN' NooR nEN COMPANY, or BOSTON,-MASSAGHUSETTS, A CORPORATION or MASSACHUSETTS GLAZED STRUCTURE Application. filed June115,

This invention relates to glazed structures,

such as skylights, and aims to improvesuch 7 structures, to make them less subject to cor rosive action, and to increase their strength and durability; I

The invention will be best understood by reference to the following description, when taken in connection with the accompanying drawings of-one specific'embodiment thereof, while its scope will be more particularly pointed out in the appended claims.

In the drawings; a

Fig. 1 is a plan of a portion of a skylight embodying the invention; 7

Fig. 2 is a sectional view, on an enlarged scale, on line 2-2 of Fig. 1;

Fig. 3 is a sectional view, on an enlarged scale, on line 33 of Fig. 1;

Fig. 4 is a sectional view, on an enlarged scale, on line 44 of Fig. 1; and

Fig. 5 is a perspective view ofa portion of the glazed structure.

Referring to the drawings, andto the embodiment of the invention which is illus trated therein, and having reference at first to Fig. 2, there is shown a glazed structure comprising two glass members 10, having adjacent edges separated by a space 11.' These members are supported by an underlying support comprising an upper bar 12 and a lower bar 13. In the present example, the upper bar is'T-shape'd in cross section, and is commonly called a T-bar. In this instance,'the lower bar is L-shaped in cross section, and is commonly called an angle bar. The lower bar presents a gutter, or trough 14, which receives water which may leakthrough the joint above, and water of condensation forming on the inside of the glazed structure. The two bars are secured to each other at intervals by pairs of clips 15 and bolts 16, the latter extending through the clips and through. an interposed vertical web angle bar.

The lower edge of the web 17 of the T-bar is separated from the angle bar by a space 20. This is of importance for two reasons first, by spacing the bars apart at this point,

1928. Serial K012855226. I corrosion is greatly diminished, and second, because a channel 1s provided for the ready escape of water. Heretofore, the upper and lower bars have been brought together at this point, and it has been found that considerable corrosion takes place, possibly due to cap1llary attraction, which tends to retam the water and keep the joint moist for a long period of time. Once corrosion has started, it increases rapidly and scale forms, thus impeding the flow of the Waters, and making the corrosion still worse. By spacing thetwo bars as shown, all capillary attraction is avoided, the water is conducted away rapidly, the parts dry quickly, and little if any corrosion takes place. As aresult, the structure requires less attention, and has a longer life. The clips are of course so formed that they are a considerable distance above the bottom of the trough, and do not obstruct the fiowof water. I

At intervals along the T-bar, there are saddles'21, which in practice are made of suitable non-corrosive metal such as brass. These saddles are laid upon the top of the T-ba-r, and are then bent downwardly and inwardly, as at 22, beneath flanges 23 which constitute the head or top of the *T-bar. These saddles form anchorages'for clamping screws '24, whose heads are appropriately secured to the saddles. A strip of cushioning material'25, such as wool felt, is superimposed upon the T-bar and upon the saddles, and presents a cushioning support for the margins of the glass members 10; This strip of course is perforated to receive the screws. Superimposed upon the glass memhers is a strip 26 ofsuitable materiahsuch as saturated felt, which'extends across the space between the edges of the glass, and covers the opening. This strip is perforated to receive the screws" Superimposed upon this strip is a metallic cap 27,-herein 'a channel-like bar of non-corrosive metal havfact that the downwardly-directed edges 28 of the cap bite into the strip prevents the edges from spreading apart under the stress caused by screwing the nuts down, and tightening the clamp constituted by the saddles, screws, nuts and cap. The structure is therefore strong, but light, and there is little if any tendency for it to leak. o 7

The bars 12 and 13 constitute arafter, whose upper end (see Fig. 4) at the ridge is secured to a plate 30, as by angle brackets 31 and bolts 32 and 33. The lower end of the rafter (see Fig. 3) is similarly secured as by angle brackets 34 and bolts 35 and 36 to an oppropriate support, hereina flange 37 presented by anrangle barl38, extending transversely of the'rafters. The'lower end of the bar 12 isseparated from the flange 37 by a space 39, which prevents water from lodging at this point, and causing corrosion. Any water which would otherwise tend to lodge here is freelto run down beneath the angle bar 38, which has a flange 10 resting upon a series of spacing blocks 41, to which the flange is secured as by bolts 42, which extend through and support the structure upon brackets 43 resting upon a curb a l. In case the latter is made of concrete, as in the present' example, each bracket has, a vertical portion 45 and a horizontal portion i6 molded into the concrete. 1

Having thus described one embodiment of the invention, but without limiting myself thereto, what I claim and desire b Letters Patent 'to secure is:

'1. In a glazed structure, the combination of upper and lower bars parallel throughout,

the lower bar presenting a gutter and the 7 upper bar extending into said gutter but separated throughout from the lower bar, means by which said bars are secured together, and

glass members having adjacent edges extending lengthwise of and supported by said upper bar. A i

2. In a glazed structure, the combination of'upper and lower 'bars parallel throughout, the lower bar presenting a gutter and the upper bar. being above and separated throughout from said gutter, means by which ends of said inclined bars, brackets supporting said inclined bars on said horizontal bar and maintaining said space, brackets beneath and supporting said horizontal bar, a watershedding plate superimposed upon the second-mentioned brackets below said. inclined bars and below said horizontal bar, and a curb which supports said brackets.

5. In a glazed-structure, the combination of a concrete curb having a vertical, inner face, a bracket having a horizontal portion superimposed upon said curb, a vertical portion having one side flush with said vertical face and three sides embedded in said curb, and a second horizontal portion completely embedded insaid curb and extending from said vertical portion toward the outer face of said curb, a glass supporting bar supported by said bracket, and glass supported by said bar.

6. In a glazed structure, the combination of a concrete curb having a vertical, inner face, a bracket having a horizontal portion superimposed upon said curb, a vertical portion having one side flush with said vertical face and three sides embedded in said curb, and a second vertical portion extendingup= wardly from said second horizontal portion and completely embedded in said curb, a glass supporting bar supported by said bracket, and glass supported by said bar. 1 7. In a glazed structure, the combination of a concrete curb having avertical, inner face, a bracket having a horizontal portion superimposed upon said curb, and a vertical portion completely embedded in said curb, a glass supporting bar upported by said bracket, and glass supported by said bar.

i In testimony whereof, I have signed my name to this specification.
